I have tried to install several times but most of the times i get the error, but sometimes it works fine. When i checked digital signature on SP2 executable it says “Digital Signature is not valid”. i have checked the same on SP1 executable it says “This Digital signature is OK” is Invalid Digital Signature is the problem which causes “File is Corrupt” error. Screenshots of SP1 & Sp2 Attached. I have downloaded SP2 3 times & i am not using any Download Booster/Accelarator.
